Export tasks

Export tasks write files or processing results from a data volume to a target connector. After creating a task, check task status and file results before confirming that the export is complete.

Export destinations

Export destination	Selectable sources on the current creation page	Final data location	Additional selections on the page
OSS or standard S3	Original files or processing results	A path in the selected connector’s bucket	Connector, target path, and compression method.
MatrixOne	Parsed or vectorized processing results	A database table in the selected connector	Connector, database, existing or new table, and column mappings.

Create and confirm an export task

1. Select files to export. For MatrixOne exports, the current page shows only parsed or vectorized processing results. For object storage, you can select original files or processing results.

2. Select the target connector. For object storage, enter a target path and compression method. For MatrixOne, select a database and an existing or new table, then configure column mappings.

3. Call Create a task. When the request is accepted, record the task ID.

4. Use the task ID to get task status and list export files. The export is complete when the counts of waiting and running files are both 0 and the failed count is 0.
